Abstract: Dense TiC-Ni cermets TH20 and TH30 were produced by self-propagating high-temperature synthesis and pseudo heat isostatic pressing. The influence of process parameters
on densities was investigated. Cermet mainly consisted of TiC particles and Ni-binder. TiC skeletal structure was enveloped by continuous Ni-binder phase. The interfacial bonding
between TiC and Ni was found to be of a good quality. High dislocation existed near the interface and inside the Ni-binder phase, some residual carbon exists in
reaction product. Meanwhile transverse rupture strengths of TH20 and TH30 were both close to those produced by conventional technology.
